Final Answer
Step-by-step Solution
Specify the solving method
Factor the trinomial $x^2-5x+6$ finding two numbers that multiply to form $6$ and added form $-5$
Thus
Simplifying
Evaluate the limit $\lim_{x\to3}\left(x-2\right)$ by replacing all occurrences of $x$ by $3$
Subtract the values $3$ and $-2$
